SYRINGE Filed Feb. 2l, 1929 Patented Sept. `17, 1929 UNITED STATES FREDERICK W. HAMES, OF ATLANTA, GEORGIA PATENT oFFi SYRIN GE Appiicauon. sied February 21, 1929. serial No. 341,697.y

transversely disposed elongated nozzles and lateral nozzles disposed longitudinally of the body portion, the latter nozzles being arranged between the first mentioned nozzles for spraying the gum margin adjacent to the teeth to treat the gums for various diseases of the gums.

A still further object of the invention is the provision of a pluralityof spaced nozzles, the spaces between the nozzles being approximately the distance equal to the widths of teeth, so that the nozzles will be guided to their proper positions to direct sprays between the adjacent edges of teeth.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed. it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit ofthe invention.

Referring to the drawing Figure 1 is a 'plan view of a syringe constructedv in accordance with the presenty invention.

Figure 2 is a sectional view taken on line 2-2 of Figure 1.

Figure 3 is a sectional view taken on line 3 3 of Figure 2.

Figure 4 is a bottom plan view of a modified form of the invention.

Figure 5 is a sectional view taken on line 5-5 of Figure 4.

Figure 6 is a side elevational view illustrating a still further modilied form ofr the invention.

Referring to the drawing in detail, the syringe includes a body portion indicated by the reference character 5, ythe body portion "l being tubular in formation and tapered tokwards the dischargeend thereof, as clearly shown by Figure 1 of the drawing. n

The outer extremity of the body portion 5 n is curved laterally as at 6 and flattened providing an elongated discharge opening 7 at the end of the bodyportion., Spaced from the laterally extended end 6, is a transverse nozzle 8,.whicli also elongated tocausethe liquid passing from the nozzle to take the i' formof a wide spray.r The distance between the end portion (iand .nozzle 8 is approXif mately the same as the width of a tooth so that when the syringe is positioned, kthe nozzles may be placed over the adjacent edges of teeth tothe end thatthe sprays'of liquid pass.-

ing from the nozzles will bedirectedrto points between the f adjacent edges of the teeth.

Lateral elongated nozzles 9 extend atoblique angles with respect to the body portion 5 rand are arranged between kthe nozzles 7 and 8 so that when the syringe is positioned for spraying between adjacent teeth, the nozzles 97'or the ,nozzle 9 adjacent to the gumline will spray the yteeth at the gum line to the end'that' medicine for ktreating gum diseases maybe directed to thegum, at the place of infection.

, In Figures 4 and 5 of the drawing ythe body j portion is provided with slits 10 disposed lon'- the sides of the body portion to directsprays against the teeth at the gumfline. In the form of the invention as shown by Figure gitudinally thereof and arranged adjacent to l the end of the body portion extends laterally as at 11 providing a nozzle, and a pair of that when the bulb has been filled with liquid. for spraying the teeth, the bulb when pressed, will act to force theliquidfthrough the body portion and nozzles to accomplish the pur-` pose of the invention.

While I have shown and described a bulb for forcing the liquid through the body portion, it is to be understood that this body portion may be used in connection with any type of forced feed mechanism, without departing from the spirit of the invention.

I claim:

l. A syringe of the class described including a tubular body port-ion, one end of the body portion being extended laterally defining a nozzle, and the end of said nozzle being flattened providing an elongated opening.

2. A syringe of the class described includ ing a tubular body portion tapered towards its outer end, the outer end of the body portion being Hattened and extending laterally defining a nozzle, and an elongated trans- Versely disposed nozzle secured to the body portion in spaced relation with the first men tioned nozzle. y

3. A syringe of the class described including a tubular body portion, nozzles having elongated openings, disposed in spaced relation with each other adjacent to one end of the body port-ion, said nozzles being elongated transversely of the body portion, and nozzles elongated longitudinallyof the body portion and disposed between the first mentioned nozzles. Y

Ll. A syringe of the class described including a tubular body portion, the discharge end of the body portion being curved laterally and flattened defining an elongated discharge opening, a nozzle secured to the body portion in spaced relation with the rst mentioned nozzle, the last mentioned nozzle being elongated transversely of the body port-ion, and said body portion having elongated openings disposed laterally thereof and arranged between the firstinentioned nozzles.

In testimonythat I claim the foregoing as my own, I have hereto affixed my signature.

FREDERICK W. HAMES.
